Method and Device for Improving Audio Quality in a Mobile Radio Network

1. Procedure to improve the audio quality in a mobile radio network, with which a tone control that is switched into one of the communication connection's corresponding audio paths that, dependent upon the types of end device(s) or equipment being used in the connection, influences the audio quality in the audio path, in that a frequency response of a sound in the audio path is changed, and further comprising a base station controller, as well as a mobile switching center, that determines the end device type(s) by query of a mobile equipment identification and assigns to the appropriate end device type corresponding pre-determined parameters, which serve to adjust the tone control.

2. Procedure, according to claim 1 , is characterized by the influence of audio quality that is different in the connection direction from the caller to the called user and from the called user to the calling user.

3. Procedure, according to claim 2 , is characterized by the parameters that are stored for all marketable mobile radio device and equipment in a data storage (memory) and can be recalled when needed.

4. Procedure, according to claim 3 , is characterized by the fact that stored parameters of the tone control of the corresponding audio path are configured based on the type of end device.

5. Procedure, according to claim 4 , is characterized by the parameters that are transferred by one of the mobile switching centers or another network component supplied control signal to the tone control.

6. Procedure, according to claim 5 , is characterized by the tone control that is switched into the audio path in the area of the mobile switching center or the base station control.

7. Procedure, according to claim 5 , is characterized by the tone control that is switched into the audio path in the area of the code conversion equipment (Transcoder/Rate Adaption Unit).

8. Procedure, according to claim 7 , is characterized by the tone control that is adjusted dependent upon the users' individual features.

9. Devices or equipment to complete the procedure, according to claim 8 , encompassing a tone control that is switched into a communication connection's audio path.

10. Equipment, according to claim 9 , is characterized by the tone control that is located in the base station control.

11. Equipment, according to claim 9 , is characterized by the tone control that is located in the mobile switching center.

12. Equipment, according to claim 9 , is characterized by the tone control that is part of the code conversion equipment (Transcoder/Rate Adaption Unit).

13. Equipment, according to claim 9 , is characterized by the tone control that is connected or switched before or after the code conversion device (Transcoder/Rate Adaption Unit).

14. Equipment, according to claim 9 , is characterized by the tone control that includes a multiplicity of tone control units, which correspond in each case to an audio path.

15. Procedure to improve the audio quality in a mobile radio network, with which an equalizer that is switched into one of the communication connection's corresponding audio paths that, dependent upon the types of end device(s) or equipment being used in the connection, influences the audio quality in the audio path, in that a sound in the audio path is changed, and a base station controller, as well as a mobile switching center, that determines the end device type(s) by query of a mobile equipment identification and assigns to the appropriate end device type corresponding pre-determined parameters, which serve to adjust the tone control.

16. A method for improving audio quality in a mobile radio network, comprising: identifying a type of end device in a communication connection by query from a base station controller, as well as a mobile switching center, of a mobile equipment identification for the end device; accessing pre-determined parameters for adjusting a tone control in an audio path of the communication connection corresponding to the identified type of end device; and influencing a quality of audio in the audio path by changing a frequency response of a sound in the audio path by the tone control according to the pre-determined parameters.
